Study of NEO-201 in Solid Tumors Expansion Cohorts

The experimental drug called NEO-201 (the "study drug") is a monoclonal antibody that is being tested and is not approved for use in the United States by the FDA. As stated above the RP2D was determined at 1.5 mg/kg and in the current Expansion Phase it will be administered in combination with pembrolizumab. . A safety lead in will be conducted in the first 3 to 6 subjects to evaluate toxicity prior to expanding accrual. The safety lead-in will be 42 days in length, consisting of 1 dose of pembrolizumab and 3 doses of NEO-201 followed by a 2-week assessment for safety, in subjects with any of the expansion cohorts' targeted disease types. The third patient in the safety lead in must complete the 30-day assessment (1 dose of pembrolizumab and 3 doses of NEO-201 followed by a 2-week safety evaluation) and be evaluated for toxicity prior to treating additional patients. Following completion of the lead-in, expansion cohorts will accrue subjects with NSCLC, HNSCC, cervical and uterine cancers who progress on frontline therapy.
